Cast nylon modified with laurolactam was prepared by activated anionic copolymerization under the adiabatic condition.Its mechanical properties were studied.
Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer were used to prepare the amphiphilic polymer by soap-free microemulsion pentamer copolymerization.
Two series of thermotropic liquid crystalline polyureas were synthesized by the copolymerization of benzidine (or o-tolidine),1,6-hexane diamine and 2,4-toluene diisocyanate.
Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate.
